Marsh Wren    Cistothorus palustris

Conservation Status

General Status in Canada : Secure

COSEWIC Status : Not Assessed

Breeding Bird Surveys indicate North American populations have changed little between 1966 and 2007 and numbers are thought to be relatively stable. Loss of wetland and marsh habitats due to draining and conversion to agricultural lands has likely impacted Marsh Wren breeding distribution locally. In areas where recent, large-scale wetland restoration and conservation programs have re-established breeding habitat, Marsh Wrens quickly re-colonize areas where they were once extirpated. Marsh Wrens are prone to fatal collisions with lit transmission towers and buildings during their nocturnal migrations.
